Flou

"Jason Freeman is an Associate Professor of Music in the College of Architecture at Georgia Tech. 

Flou (pronounced 'flew') is not exactly a game; you do fly a ship through space, but you cannot shoot anything, score points, or win or lose. The focus, rather, is on the soundtrack: as you navigate through a 3D world and zoom through objects in space, you add loops and apply effects to an ever-evolving musical mix. You can also design your own worlds to fly through and share them with other Flou users." -- from Turbulence
